ment at Oxford, it was found that the hindwings in four out 

 of the fourteen showed a very definite tendency towards the 

 production of " tails." Furthermore, the hind margin of these 

 wings, instead of being evenly rounded, presented, in diilering 

 degrees in the four specimens, a squarish outline with the 

 rudimentary "tail" at the angle. Some of the specimens 

 closely resembled the hippocoon figured by Prof. Poulton 

 in Trans. Ent. Soc. 1906, pi. XIX, fig. 3, but in one specimen 

 at least the undulation of the margin was far more reduced 

 except at the "tail," and the appearance was therefore more 

 square-like. Two females only out of all those comprised 

 in the five other families showed a similar condition. These 

 appeared in family I. Mr. Lamborn hoped to repeat the 

 experiment on a larger scale, and carry it out more fully, in 

 order to obtain conclusive evidence as to the effects of a 

 lowered temperature upon this species, 



Russian Parnassius apollo.— Mr. J. A. Simes exhibited a 

 short sei'ies of P. apollo from the Government of Viatka, with 

 a series fi'om the Alps of Dauphiny and Switzerland for 

 comparison. The Russian examples were characterised by 

 their great size and by the similarity of coloration in both 

 sexes, while the Alpine specimens showed a considerable 

 degree of sexual dimorphism. 



Families op Papilio dardanus. Brown, bred in Natal 



FROM FEMALE PARENTS OF THE TROPHONIUS, WeSTW., FORM, BY 



Miss M. E. Fountaine and Mr. G. F. Leigh. — Prof. Poulton 

 said that, at his desire. Miss Fountaine had kindly prepared 

 the following account of the extremely interesting family 

 reared by her in 1909 — the only Natal family at present 

 known in which cenea is other than the most numerous of all 

 the forms. 



''■ On the 5th of January, 1909, in Stella Bush, near Durban, 

 (Natal) I caught a very old $ specimen of Papilio dardanus, f. 

 trophonius, which I kept, hoping to obtain ova. On January 

 7th, she laid 28 ova (one of which I am inclined to think must 

 have escaped my notice the day before). And up to January 

 11th a few more were laid every day, till, the number having 

 reached 45, I released the 9, in the ' glades.' On January 

 10th, I larva hatched out, on January 11th, 27 larvae, each
